Getting old. It's better than the alternative, right? But the way Britons think about retirement and old age has changed enormously since the second world war. Some of us seize the chance to emigrate to sunnier places. Others find themselves living in a society with a tendency to regard the elderly as an asset-rich burden on the public finances.

Should the state pension age keep rising? Are politicians, many of whom never truly retire, the right people to order the rest of us to keep working for longer?

Ros Taylor talks to Helen McCarthy, Professor of Modern and Contemporary British History at the University of Cambridge. She is writing a social and cultural history of retirement since 1945, to be published by Penguin (Allen Lane). Her article on Brits retiring overseas is available to read.

The extract from Beveridge: The Problem of Old Age is at the Socialist Health Association.

Jeremy Seabrook wrote about old age for the Guardian in 2010. His books include A World Growing Old.

The Thames TV report about pensioner Dick is available on YouTube, as is the 1981 interview with Margaret Thatcher and a 1969 BBC documentary about retirees abroad.

I also drew on the Guardian's obituary of Kingsley Amis, Commons library briefings on pensions in the UK and the communication of state pension age increases for women born in the 1950s, Finishing the job: launching the Pensions Commission and the Institute of Fiscal Studies' history of state pensions,

Hugely unpopular, the poll tax helped bring down Margaret Thatcher. But she had plenty of warnings. Why did the Tories press ahead anyway? Why do ageing lefties remember the protests with nostalgia? And what are the lessons for anyone who dares to try to reform property taxes?

Ros Taylor was talking to Tony Travers, the co-author of Failure in British Government: The Politics of the Poll Tax and a Professor in Practice at the London School of Economics.

I also drew on The Poll Tax Rebellion in Haringey, a BBC Four interview with David Mellor, the Centre for Policy Studies' Of Dukes and Dustmen: Cautionary Rhymes on the Community Charge, CSpan footage of Prime Minister's Questions with Margaret Thatcher and Neil Kinnock, BBC news reports of the riot, a 1997 edition of Newsnight, Poll tax is history in the Guardian, and a Warwick Economic research paper: The UK poll tax and the declining electoral roll: unintended consequences? by Jeremy Smith and Iain Maclean. The description by Colin of the poll tax riot is from Bollocks to the Poll Tax by Colin Revolting and was read by Ned Palmer.

Britain had only one colony in mainland South America – a coastal state next to Venezuela that it grabbed from the Dutch more than 200 years ago. This was British Guyana.

By the 1950s, Britain had had enough – and the plan was to hold elections so the Guyanese could take over. But then the man they elected said he was inspired by Soviet Russia. The story of Britain's long exit from Guyana takes in the CIA, MI5, rigged elections and a beautiful American whom JFK considered one of the most dangerous communists in the western hemisphere.

Ros Taylor spoke to historian of Guyana Clem Seecheran, who is the author of Sweetening Bitter Sugar: Jock Campbell, the Booker Reformer in British Guiana 1934-1966, and Rod Westmaas of Guyana Speaks. You can hear Seecheran talking at more length at the National Archives.

Cheddi Jagan's life and work is archived at the Cheddi Jagan Research Centre, which also includes declassified British documents relating to the suspension of the constitution in 1953, from which the readings in this episode were taken. This 1866 history of British Guyana is also interesting. I drew on the National Security Archive's account of the CIA's involvement in British Guyana and on MI5's in The Defence of the Realm: The Authorised History of MI5 by Christopher Andrew,

You can see and hear Cheddi Jagan in the footage from News Room Guyana.
